Annual Award for Clinical Research in Periodontology

PMID: 23484166

Every year the American Academy of Periodontology (AAP) presents the Clinical Research Award, sponsored by Quintessence Publishing Company, to an outstanding published scientific study with direct clinical relevance in periodontics. The winning study must follow scientific methods for a human study, be published in English in a scientific journal during the previous calendar year, directly apply to the practice of periodontics, and provide new information that can be readily used by practitioners in the evaluation of patients.

The 2012 Clinical Research Award was presented to the study titled “Periodontal Regeneration Versus Extraction and Prosthetic Replacement of Teeth Severely Compromised by Attachment Loss to the Apex: 5-Year Results of an Ongoing Randomized Clinical Trial,” (P. Cortellini, G. Stalpers, A. Mollo, and M. S. Tonetti, J Clin Periodontol 2011;38(10):915–924). The study authors accepted the award at the AAP’s 2012 Annual Meeting in Los Angeles, California.

The study, which was published in the October 2011 issue of the Journal of Clinical Periodontology, compared clinical and patient- based outcomes following periodontal regeneration or extraction and replacement of hopeless teeth with chronic periodontic lesions and/or attachment loss. Regenerative strategies were applied to 25 hopeless teeth, while 25 additional hopeless teeth were extracted and replaced with conventional implant-supported fixed partial dentures. Twenty-three of the 25 regenerated teeth showed clinical improvement after 1 year. The 23 successfully regenerated teeth (92%) were in good health and function at the 5-year examination visit, and 84% did not develop biologic complications during the recall period. All fixed partial dentures survived the 5-year follow-up period, and 83% were free from biologic complications. All patients consistently reported comfort in function at the experimental test and control groups. The study suggests that regenerative therapy can be applied to hopeless teeth and has the potential to change their prognosis. The technology may be a suitable alternative to extraction of severely compromised teeth with infrabony defects.
